C Language-Snake Game Project
Initialization of the snake
The initialization of the snake is actually the initialization of a two-dimensional array. The two-dimensional array stores two values, which contains the coordinate information of the snake's body. The initial position of his appearance is the middle position of the simulated coordinate.
The movement of the snake
The movement of the snake is achieved by changing the coordinates of the two-dimensional array. For example, when the snake advances one unit to the right, the coordinates of each body position of the tail are changed, and the direction of the tongue, the body and the tail of the snake are changed at the same time. In this way, the snake has moved forward by one unit overall.
Snake growth
When the snake eats normal food, the length of the snake will increase. Increasing the length of the snake means adding a two-dimensional array to the position of the food and turning this position into the head of the snake.
Death of snake
When the snake hits an obstacle, itself, or clears a level, the death of the snake is the destruction of the two-dimensional array.
Food production
The location of food is random. These factors are determined by random numbers obtained through random functions. The location of food cannot appear on obstacles and boundaries.
Control keyboard input
Change the direction of movement in the module by obtaining the W (up), S (down), A (left), and D (right) input by the keyboard, thereby affecting the movement direction of the snake.
